JOHN B. DADE, OF FRANKFORT, NEW YORK.

VISE.

To all whom it may concern:

Be it known that I, J oi-IN B. DADE, a citizen of the United States,residing at Frankfort, in the county of Herkimer and State of New York,have invented certain new and useful Improvements in Vises, of which thefollowing is a specification, reference being had therein to theaccompanying drawing.

My invention relates to a vise and I declare the following to be a full,clear, concise and exact description thereof sufficient to enable anyone skilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings in which like referencecharacters refer to like parts throughout the specification.

The object of the invention is to provide a vise that will be efficientin operation and of simple construction whereby the same may be cheaplymanufactured.

The salient features of the device embody a jaw adjustably disposedrelative to a slidingly mounted counter jaw which is actuated by theintermediate movement of an ec,- centric or cam controlled by a leverhandle adapted to be retained in any position in its arc of movement byfriction means.

Other features will appear from the drawings, in which:

Figure 1 is a side elevation of the device partially in section; Fig. 2is a plan of the vise; Fig. 3 is a transverse section taken on the line3 3 of Fig. 1; Fig. 4 is a transverse section taken on the line L--l ofFig. 1; Fig. 5 is an end elevation, somewhat diminished in size; Fig. 6is a perspective view, enlarged, of a bolt employed on the device; Fig.7 is a perspective of a plate, showing more particularly certainshoulders; Fig. 8 is a detail perspective of certain disks; Fig. 9 is adetail perspective of a sleeve; and Fig. 1() is a plan of the detailshown in Fig. 7; Fig. 11 is a plan view from beneath of Fig. 8, made tothe scale of Fig. 1.

Referring more particularly to the drawings, the body of the device ispreferably constructed from a metallic casting 1, having base orplatform 2, laterally recessed, as at 3-3 etc. for the suitable mountingof the device upon any proper standard;

Upon opposite longitudinal sides of body 1, there are flanges 1 -4adapted to slidingly support jaws 5 and 6 having hardened faces 7 and 8respectively, held to said aws 5 and 6 by bolts 9, whose heads 10 arecountersunk in the adjacent portion of said jaws 5 and Specification ofLetters Patent.

6. Faces 7 and 8 may be replaced by new ones whenever same become wornor destroyed by use of the device. Jaw 5 is adjustably held relativelyto jaw 6 by pivotally mounted rack 11 having depending member 12,recessed at 13 for the vertically adjust` able reception of the adjacentend of rack 11 upon stud or bolt 14 whose head 15 is counter sunk andremote end threaded at 16 whereby to be mounted in a correspondinglythreaded bore in body 1. Said depending member 12 of rack 11 is elevatedor lowered within the limits defined by recess 13 by means of set screw17 mounted in the lower central part of .member 12. The remote portionof rack 11 has a depending member 18 recessed transversely at 19 for thereception of one end of lever 20 pivotally mountend to said member 18 bybolt or screw 21. Said lever 20 is fulcrumed upon bolt 22 supported bylugs 253-23, integral with body 1. Bracket 11 is held in elevatedposition whereby its teeth 24: will be normally in mesh with teeth 25upon the under surface of jaw 5, by coiled spring 26 mounted in recess27 of the casting or body 1. In order to lower said teeth 211 of rack 11so as to be out of mesh with teeth 25 of aw 5, it is only necessary topull upward upon the outer end of lever handle 20, which lever willcause rack 11 to swing downward upon bolt 1-l as a fulcrum. Saidpivotally supported end is vertically adjustable by the screwing orunscrewing of set screw 17.

Obviously, from the foregoing description, jaw 5 may be moved relativelyto jaw 6 whereby to adapt the vise to articles of different dimensions.

Jaw 5 is confined to sliding movement along flanges 1*4 by cleats 28-28secured to said jaw 5 by bolts or other suitable means 29-29 and adaptedto project under the lower surfaces 30-30 of fianges 1 -4.

Jaw 6 is similarly confined to flanges 1 4 by cleats 31-31 held to saidjaw 6 by bolts 32-32 and is slidingly actuated to approach or recedefrom jaw 5 whereby to hold or release an object between jaws 5 and 6 byan eccentric mechanism now to be described.

Integral or otherwise connected with jaw 6 are two bearing brackets33-33 between which there is pivotally mounted by pin or bolt 34, end 35of metallic strap 36. The remote end 37 of said strap 36 embraces disk38 having eccentrically disposed underneath the same and preferablyintegral therewith a disk 39 which is shouldered at 40 and 41 tocorrespond with shoulders 42 and 43 of rectangular plate 44, slidinglymounted in ways or grooves 45 of body l.

Above disk 38 or on the reverse side from that on which disk 39 isdisposed is a hub or sleeve 53 concentric with disk 39 but eccentricwith disk 38 with which it may be integral.

Plate 44, and disks 39, 38, and hub or sleeve 53 are held in assembledposition, whereby disk 38 is eccentric to disks 39 and hub or sleeve 53by wrist-pin 49 having rectangular shaped head projecting onk eitherside under shoulders 51-51 formed in body 1, and slidingly mounted inrecess 52 provided in casting or body l. Said stationary adjustableplate 44 is held at any location along Ways or grooves 45 45 by means ofcollar 46 assembled upon wrist-pin 49 and bearing partially againstshoulder 55 thereof and also against plate 44 when the parts areassembled. Said collar 46 bears against stationary adjustable washer 47held rigidly in vertical location by nut 48 screwmounted upon wrist-pin49.

The central portion of body l is recessed at 56.

The operation of the device is eected in the following manner, namely:Nut 48 is tightened upon wrist-pin 49 to force sleeve 46 upon plate 44and head 50 of wrist-pin 49 in contact with shoulders 51-51, whereby toconfine said wrist-pin 49 and parts assembled thereon, namely plate 44,disks 39, 38, 37, sleeve 46, to a given position along ways or grooves45-45, whereby said wristpin 49 may be functioned to act as a fulcrumfor the longitudinal reciprocation of jaw 6, which is actuated by disk38 eccentrically controlled by lever handle 57 keyed at 58 to l hub orsleeve 53, integral with disk 38. J aw 5 is also adjusted with referenceto nearness to jaw 6 by means of teeth 25 thereon and teeth 24 of rackl1 which may be lowered from mesh with teeth 25 by pulling upward onlever handle 20. An object is held between jaws 5 and 6, whereupon thehandle or lever 57 is moved from the position indicated in Fig. 5 totheposition indicated in Fig. 2, the pull being a convenient one for aright handed operator, though the parts may be reversed for a lefthanded operator. In order to hold said handle 57 in this last positionwhereby an object between jaws 5 and 6 will be firmly confinedtherebetween, or in other words in order to prevent handle 57 fromslipping backward to its original position, the invention contemplatesthe employment of shoulders 42 and 43 of plate 44 which shoulders arerounded o' at 58 and 59, so that shoulders 40 and 41, which are likewiserounded offV at 60 and 6l will ride upon said shoulders 42 and 43 andthereby effect a forcible contact of the said shoulders with each other,which contact will in turn hold the handle 57 rigidly in any desiredlocking position. This locking means is effective for the reason thatany wear may beI taken up by tightening nut 48 upon wristpin 49.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

l. In a device of the character described, the combination with a baseof two jaws each adapted to be moved and fiXed thereon, one of themhaving a toothed face on its lower surface, a bracket having teeth toengage with the said toothed face, the said bracket having portionsdepending below a fixed part of the base, a spring member acting topress the Ibracket upward from the base, means at one of the dependingportions to adjust the bracket relatively to the base and lever means atthe other depending portion to raise or lower the bracket, by thecoperation of which means to put the teeth of the bracket into or out ofcontact with the toothed face of the jaw.
